Intravitreal Injections Intravitreal Injections This material will help you understand your intravitreal injection treatment and what you can expect. What are intravitreal injections? An intravitreal injection (IVI) is a shot of medicine into your eye using a thin needle. The inside of your eye is filled with a gel-like fluid called the vitreous (vit-ree-us). The doctor or nurse will inject the medicine through the front of the eye into the vitreous, near the retina at the back of the eye (see picture on right). Image courtesy of the Collaborative Ocular Melanoma Study Group The medicine used will depend on your condition being treated. IVIs are used to treat many eye problems, including macular degeneration, diabetic retinopathy, and some cases of eye cancer. What can I expect before my treatment? There are no special preparations for IVI. You should eat normally and take all your regular medicines before you come in. Let your doctor know any medications you are currently taking, as well as any allergies you have. Kellogg Eye Center Intravitreal Injections 1 This treatment is performed in your doctor’s office, so you will be able to go home the same day. If you do not feel comfortable driving after your treatment, you may want to bring a friend or family member with you to drive you home. What can I expect on the day of my treatment? On the day of your IVI, you will come to the Kellogg Eye Center Oncology Clinic. First, you will be given eye drops to dilate (widen) your pupils. Your doctor will then have you lie down in a comfortable face-up position. S/he will clean your eyes and eyelids to help prevent infection. Then s/he will numb your eye using eye drops or an injection. The doctor will place a small device on your eye to keep your eyelids open. Once this is in place, s/he will inject the medicine into your eye using a thin needle. You will likely feel some pressure, but it should not hurt. After the injection, your doctor will put antibiotic ointment on the eye to further prevent infection. The entire treatment takes about 15-30 minutes to complete. What can I expect after my treatment? After your IVI, you may sense more pressure and/or have a gritty feeling in your eye. You should not feel any pain. You may notice bleeding in the white part of your eye or pink tears. You may also see floaters in your field of vision. These effects should lessen or go away within a few days. Your eye doctor will prescribe antibiotic eye drops or ointments, which you should use as directed. You should not rub your eyes for several days after your IVI. You should also avoid swimming for at least 3 days. Kellogg Eye Center Intravitreal Injections 2 You will see your doctor about 1 month later for a follow-up visit. You may need to have multiple injection treatments depending on your condition. Are there any complications related to intravitreal injections? As with most procedures, there is a chance of complication from IVI. Your doctor will discuss many of these with you when you consent to treatment. Some of the more serious complications from IVI include inflammation, bleeding, infection (endophthalmitis), retinal tear or detachment, or an allergic reaction from the medication used. These may be treated if caught early. Call your eye doctor right away if you have any of these symptoms (or any others that worry you): • Increased pain not helped by Tylenol® (Acetaminophen) • Change in vision • Any redness or swelling around the eye gets worse If you call the clinic after clinic hours, you will be told how to get in touch with the eye doctor on call. There is an eye doctor on call every day of the year.

  • Informed Consent for Lucentis Tm (Ranibizumab) Intravitreal Injection
    PATIENT _________________________________________DATE __________________ OD OS INFORMED CONSENT FOR LUCENTIS TM (RANIBIZUMAB) INTRAVITREAL INJECTION INDICATIONS Age-related macular degeneration (AMD) is the leading cause of blindness in people over 50 years of age. There are two types of macular degeneration: dry and wet. In the “wet” form of AMD, abnormal blood vessels grow in the back of the eye. Sometimes these vessels leak blood or fluid that causes blurred or distorted vision. Without treatment, vision loss may be quick and severe. POSSIBLE BENEFITS, LIMITATIONS, AND ADMINISTRATION Lucentis TM works by inhibiting the growth of the abnormal blood vessels that cause AMD. It is also used to treat swelling of the macula due to MAD. The goal of treatment is to prevent further loss of vision. Although some patients have regained vision, the medication may not restore vision that has already been lost, and may not ultimately prevent further loss of vision caused by the disease. After the pupil is dilated and the eye is numbed with anesthesia, the medication is injected into the vitreous or jelly-like substance in the back chamber of the eye. Lucentis TM is administered by an injection into your eye as needed at regular intervals (about every four weeks); your ophthalmologist will tell you how often you will receive the injection, and for how long. ALTERNATIVES You do not have to receive treatment for your condition, although without treatment, AMD can lead to further vision loss and blindness, sometimes very quickly. Other forms of treatment are available. At present, there are two other FDA-approved treatments for neovascular AMD: Photodynamic therapy with a drug called Visudyne TM and injection into the eye of a drug called Macugen TM .

Wong2,3 BENCH TO CLINIC SYMPOSIA Diabetic Retinopathy: Overview of Clinical Efficacy and Evolving Applications Diabetes Care 2014;37:900–905 | DOI: 10.2337/dc13-1990 Ocular anti-vascular endothelial growth factor (VEGF) therapy represents one of the most significant advances in modern medicine. The introduction and widespread use of ocular anti-VEGF therapy for age-related macular degenera- tion heralded a new era in the treatment of vascular and exudative diseases of the retina. Its expanding indications now include diabetic macular edema and proliferative diabetic retinopathy, two vision-threatening forms of diabetic retinopathy. It is widely anticipated that ocular anti-VEGF therapy could spark a dramatic shift in the treatment paradigm for diabetic retinopathy. However, despite its clear efficacy shown in clinical trials, the dynamic landscape of evolving medical, ethical, and economic issues related to this new treatment suggests significant challenges ahead. In this article, we provide a discussion of this topic as part of this two-part Bench to Clinic narrative. Here, our Clinic contribution provides an overview of the current evidence from clinical trials on anti-VEGF therapy for diabetic retinopathy, and highlights the hopes and fears of this new treatment from clinical and public health standpoints. In the Bench narrative that precedes this contribution, Simo´ et al. provide an overview of the role of VEGF in the pathogenesis of diabetic retinopathy. Ocular anti-vascular endothelial growth factor (VEGF) therapy represents one of the most significant advances in modern medicine.

  • The Role of Topical Antibiotic Prophylaxis to Prevent Endophthalmitis After Intravitreal Injection
    The Role of Topical Antibiotic Prophylaxis to Prevent Endophthalmitis after Intravitreal Injection Philip Storey, MD, MPH,1 Michael Dollin, MD,1 John Pitcher, MD,1 Sahitya Reddy, BA,2 Joseph Vojtko, BA,2 James Vander, MD,1 Jason Hsu, MD,1 Sunir J. Garg, MD,1for the Post-Injection Endophthalmitis Study Team* Objective: To compare the incidence of endophthalmitis after intravitreal injection with and without topical postinjection antibiotic prophylaxis. Design: Retrospective case-control study. Participants: All patients treated with intravitreal injection of ranibizumab, bevacizumab, or aflibercept for a variety of retinal vascular diseases at a single, large retina practice between January 1, 2009, and October 1, 2012, were included. Methods: The total numbers of patients and injections were determined from a review of billing code and practice management records. Endophthalmitis cases were determined from billing records and from an infection log. All cases of endophthalmitis were confirmed with chart review. A 28-month period when topical antibiotics were prescribed after intravitreal injection was compared with a 9-month period when topical antibiotics were not prescribed. Patients treated during an 8-month transition period were excluded to allow for the conversion of antibiotic prescription practices. Main Outcome Measures: Incidence of endophthalmitis, visual acuity outcomes, and microbial spectrum. Results: During the study period, a total of 117 171 intravitreal injections were performed (57 654 injections during the topical antibiotic period, 24 617 during the transition period, and 34 900 during the no-antibiotic period), with a total of 44 cases of suspected endophthalmitis (0.038%; 1 in 2663 injections), 17 of which showed culture-positive results (0.015%; 1 in 6892 injections).

  • Intravitreal Injections Policy Background Anti-VEGF Agents
    Intravitreal Injections Policy Patients undergoing intravitreal injections require the care and judgment of an ophthalmologist experienced in diagnosing and treating retinal diseases as well as potential complications that may necessitate surgical intervention. The Academy strongly supports the position that all intravitreal injections should be performed only by ophthalmologists, which are licensed doctors of medicine or osteopathy. Background Intravitreal injections of air were first used in 1911 for the purpose of repairing retinal detachments.1 Since that time, intravitreal injections have been used to treat a variety of conditions, including endophthalmitis, intraocular lymphoma, cytomegalovirus (CMV) retinitis, submacular hemorrhage, vitreous hemorrhage, retinal vascular occlusive disease, diabetic retinopathy, and neovascular age-related macular degeneration (AMD). The primary benefit of intravitreal injection is the targeting of the therapeutic agent in the eye while minimizing systemic absorption. In 1998, the United States Food and Drug Administration (FDA) approved the use of the first agent for intravitreal injections, fomivirsen sodium (Vitravene®, Isis Pharmaceuticals, Carlsbad, CA), an antiviral used in the treatment of CMV retinitis. Anti-VEGF Agents The frequency of intravitreal injections significantly increased with the introduction of anti-vascular endothelial growth factor (anti-VEGF) medications. In the early 2000s, the use of intravitreal injections accelerated fueled by clinical trials and technology assessments

  • (ASRS) Statement Compounding Listening Session, June 3, 2016 Food and Drug Administration
    American Society of Retina Specialists (ASRS) Statement Compounding Listening Session, June 3, 2016 Food and Drug Administration Thank you for the opportunity to present during the 2016 listening sessions on drug compounding. On behalf of the American Society of Retina Specialists (ASRS), its members and their patients, we submit the following comments on FDA draft guidance documents. The ASRS is the largest retinal organization in the world, representing over 2700 fellowship-trained members. Retina specialists are board-certified ophthalmologists who have completed fellowship training in the medical and surgical treatment of retinal diseases. Retina patients are treated with a myriad of compounded therapies including injectable antibiotics, anesthetics, dyes used during surgery, and bevacizumab (Avastin). In general, retina doctors have access to these therapies either through 503B outsourcing facilities, or through 503A facilities pursuant to an individual prescription. However, in certain emergencies we have difficulty accessing medications needed for our patients. Limited access to compounded antibiotics for intravitreal injection We would like to thank the FDA for acknowledging the need for retina specialists to have compounded antibiotics on hand to treat emergency infections such as endopthalmitis. This scenario is described in the current draft guidance on the prescription requirement under Section 503A (line 103 – 110): “Sometimes, it is necessary for health care practitioners in hospitals, clinics, offices, or other settings to have certain compounded drug products on hand that they can administer to a patient who presents with an immediate need for the compounded drug product. For example, if a patient presents at an ophthalmologist’s office with a fungal eye infection, timely administration of a compounded antifungal medication may be critical to preventing vision loss.

  • Treatment of Acute Retinal Necrosis
    Treatment of Acute Retinal Necrosis Michael D. Tibbetts, MD,1 Chirag P. Shah, MD, MPH,2 Lucy H. Young, MD, PhD,3 Jay S. Duker, MD,4 Joseph I. Maguire, MD,2 Michael G. Morley, MD5 Objectives: To compare outcomes from patients with acute retinal necrosis (ARN) treated in the acyclovir- only era with those treated in the era of newer antiviral therapies, identify variables affecting outcomes in ARN, and evaluate strategies for fellow eye prophylaxis. Design: Multicenter, nonrandomized, retrospective, interventional series. Participants: A cohort of 58 patients diagnosed with ARN by a retina specialist at 1 of 4 referral centers between 1981 and 2008. The cohort was divided into 2 subgroups: patients treated during the acyclovir-only era (n ϭ 36) and patients treated during the current era of newer antiviral medications (n ϭ 22). Intervention: Intravenous, oral, or intravitreal antiviral medications, including acyclovir, valacyclovir, famci- clovir, valganciclovir, ganciclovir, and foscarnet; prophylactic laser retinopexy; aspirin; oral steroids. Main Outcome Measures: Visual acuity, retinal detachment, and fellow eye involvement. Results: A wide range and combination of antiviral agents are currently used for initial and long-term treatment of ARN. Outcomes from the newer antivirals era were similar to those achieved during the acyclovir- only era. In both groups, the incidence of 20/200 or worse visual acuity was 24% per person-year (P ϭ 0.91). The prevalence of retinal detachment was approximately 50% in each group (P ϭ 0.59). No variables, including prophylactic laser retinopexy, were associated with risk of retinal detachment. Two patients (3.4%) developed ARN in the initially unaffected eye.
